"Perception of waiting" sounds like a problem but isn't yet a design target. It doesn't say where the wait is happening, what's causing it, which customers it's costing the most, or what a fix would actually need to accomplish. Before I could prototype anything useful, I needed a way to find the actual problem.
I built the investigation structure while running it. Seven phases: Monitor and Frame, Explore and Identify, Ideate and Visualize, Prototype and Envision, Experiment, Refine, Optimize. The sequence exists for a reason. Monitor and Frame isn't background research — it's defining what "better" would actually mean for this context, with the people who know it. Without that grounding, a prototype risks solving for the wrong thing with high fidelity.
The decision to build the framework explicitly — to name each phase, design the activities for it, and run the whole engagement as a demonstration of a repeatable method — wasn't in the original brief. It became load-bearing when it became clear that the goal wasn't just to fix the Pro Pickup. It was to give Ferguson's CX team the tools to keep finding things worth fixing.
